Carbon-14 is a radioisotope that is used for dating biological organisms. The half-life of C-14 is 5730 years. When a one-gram sample of carbon from fresh peat is measured for radioactivity, 900 beta decays are recorded every hour. A one-gram sample of carbon is obtained from a peat deposit and is measured for radioactivity. If 113 beta decays are observed every hour, how many half-lives of C-14 have passed since the deposit was formed? A. 1/8 B.3 C.113 D.8 Approximately...

In the carbon dating process for measuring the age of objects, carbon-14, a radioactive isotope, decays into carbon-12 with a half-life of 5730 years. A Cro-Magnon cave painting was found in a cave in Europe. If the level of carbon-14 radioactivity in charcoal in the cave is approximately 16% of the level of living wood, estimate how long ago the cave paintings were made. (Hint: Let the initial amount of carbon-14 be C0. Round your answer to the nearest year.)

1. The half-life of carbon-14 is 5730 years. A sample is found to have one-eighth the original amount of carbon-14 in it. How old is the sample? 5730 years, 716 years, 45800 years, 17200 years 2. Why wouldn't you use carbon-14 dating on a piece of shell that was estimated to be 1 million years old? Sea shells do not have radioisotopes, carbon dating is only useful on plants, uranium dating is better for items older than 1/2 million years,...
